Protective glass against ionizing radiation

Abstract

An element, particularly a transparent element, including at least one glass element, configured as a protective glass against ionizing radiation and/or UV radiation, wherein at least a portion of the surface of the glass element is covered by a film that includes a substance that can be switched into at least two states.

1. An element, comprising:
 a film, said film being a substance switchable into at least two states a transparent state and a substantially non-transparent state; 
 at least one glass element having a surface at least partially covered by said film, said glass element being an X-ray protective glass having a lead content of ≧60% by weight and a lead equivalent value of 0.5 mm to 7 mm when subjected to an X-ray voltage of 40 kV to 200 kV of an X-ray tube and configured to protect against at least one of ionizing radiation and UV radiation; 
 an additional glass element which is a glass pane, said film being positioned between said protective glass and said additional glass element defining a laminated glass element and said glass pane being one of a single pane of glass configured to protect against ionizing radiation, an anti-reflective single pane, a laminated glass pane, a decorative glass pane, a single pane of a color effect glass, a heat protection glass pane and a sun protection glass pane; and 
 at least one other glass pane, said at least one other glass pane being positioned at a predefined distance to said at least one glass element, thereby defining an insulating glass element. 
 
     
     
       2. The element according to  claim 1 , wherein said lead content is >60% by weight. 
     
     
       3. The element according to  claim 2 , wherein said lead content is ≧65% by weight. 
     
     
       4. The element according to  claim 3 , wherein said lead content is >70% by weight. 
     
     
       5. The element according to  claim 1 , wherein said X-ray protective glass has a transmission of ≧80% for wavelengths in the visible light range of 420 nm to 780 nm. 
     
     
       6. The element according to  claim 1 , wherein said at least one glass element is a single pane. 
     
     
       7. The element according to  claim 6 , wherein said single pane has a thickness of between 4 mm and 25 mm. 
     
     
       8. The element according to  claim 7 , wherein said thickness is between 4 mm and 10 mm. 
     
     
       9. The element according to  claim 1 , wherein said substance is an electrochromic substance. 
     
     
       10. The element according to  claim 1 , wherein said substance is a liquid crystal substance. 
     
     
       11. The element according to  claim 10 , wherein said liquid crystal substance can be switched from a disordered non-transparent state that scatters visible light into an ordered non-scattering state, and vice versa. 
     
     
       12. The element according to  claim 11 , further comprising two polarization films, said liquid crystal substance being positioned between said two polarization films, said liquid crystal substance being configured to be switched from a lightened transparent polarization state to a darkened transparent polarization state, and vice versa. 
     
     
       13. The element according to  claim 11 , wherein said X-ray protective glass further includes a transparent conductive layer. 
     
     
       14. The insulating glass element according to  claim 1 , wherein said glass pane is one of single pane of glass configured to protect against ionizing radiation, an anti-reflective single pane, a laminated glass pane, a decorative glass pane, a single pane of color effect glass, a heat protection glass pane and a sun protection glass pane. 
     
     
       15. The insulating glass element according to  claim 1 , wherein said predefined distance between said at least one glass pane and said glass element is between 5 mm and 50 mm. 
     
     
       16. The element according to  claim 1 , wherein the element is used as protective glass against ionizing radiation in the medical field.
